Toad for DB2 V3.0 is in Beta right now (we are expecting to GA next month (July). You can check it out here: http://www.toadsoft.com/toaddb2/toaddb2beta.html

It includes numerous enhancements including the ability to compare/migrate/sync DB2 v8 and V9 objects including sequences . Moreover, you can also do some really cool stuff with it like migrating object stats, saving the migration settings for reuse, transforming source schemas/tablespaces to different schemas/tablespaces on the target etc..
